    Equation of a circle with centre (4, 3) touching the circle x to the power of 2 end exponent plus y to the power of 2 end exponent equals 1is

    Let the circle touching the circle x2 + y2 = 1, be x2 + y2 – 8x – 6y + k = 0,
    The equation of the common tangent is S1 – S2 = 0
    i.e. 8x + 6y–1–k = 0
    This is a tangent to the circle x2+y2 = 1.
    Hence ± 1 = fraction numerator k plus 1 over denominator square root of 8 to the power of 2 end exponent plus 6 to the power of 2 end exponent end root end fraction
    Þ k+1 = ± 10 Þ k = –11 or 9
    Therefore the circles are x2+y2–8x–6y+9 = 0 and x2+y2–8x–6y–11 = 0
    Hence (d) are the correct answers.
